Taillight Issue in a 2020 Chevy Silverado Trailboss

[Travis Nolting]

Hello,  

 

I have an issue with my 2020 Chevy Silverado Trail Boss and was looking to see if anyone could help point me in the right direction.  

 

I have an error message that says "Right Rear Indicator Failure" that pops up when I use the right turn signal.  It will flash 3 times as normal, then the error message pops up and it will hyper flash. The lights all still function but the right side rear hyper flashes.    I took my truck in for a routine oil change and tire rotation today and the dealership told me that it is a voltage issue and that the whole assembly needs replaced.  They also said that because the are LED lights that the total cost in fixing this issue would be just under $1200.  I did not agree to have anything completed instead am turning to the internet for  research, advice, and assistance.  I am not a mechanically inclined person and know little about fixing vehicles but almost $1200 seems extremely high for replacing a tail light assembly. 

 

The dealership also told me that there are currently no parts available or an ETA when they would be back in stock.  

 

In my research I did see some people having similar issues.  In most of those it was because they installed after market tail lights.  Mine are stock and factory OEM.  I do see them for sale online between $150-$200 through various sites.    

 

I am hoping someone here can assist me and point me in the right direction as to what I should do next in getting this issue corrected.  

 

Thanks for your time.

I have a 2014, but at 6 years old I had similar issue - ended up buying new harness for that side, all corroded up from exposure to tire "fling/crud/debris" attacking connection terminals and getting to pins.
